In the past, we only had one network stack which was called NET. The
network features were enabled for the legacy (and then only) networking
stack since commit 22353fa6b585 ("bootstd: Add some default filesystems
and commands"). Then instead on relying on NET legacy stack for enabling
networking features, the dependencies were (mostly) changed to depend on
CMD_NET in commit a0c739c184ca ("boot: Create a common BOOT_DEFAULTS for
distro and bootstd"). Then a new stack (lwIP) appeared, then CMD_NET was
made available with this new stack in commit 98ad145db61a ("net: lwip:
add DHCP support and dhcp commmand") making the networking features
possible to enable and finally commit f1e978fd54d9 ("boot: Update tests
around network symbols in BOOT_DEFAULTS_CMDS") made it explicit that we
need *a* network stack to enable some networking features.
Align the bootstd documentation with what's actually implemented as
Kconfig dependencies. Note that BOOTSTD_DEFAULTS selects BOOT_DEFAULTS
which selects BOOT_DEFAULTS_CMDS which then selects network features.
The CMDLINE symbol needs to be enabled as well for BOOT_DEFAULTS to
select BOOT_DEFAULTS_CMDS, but I don't think we need to go that far into
explaining what's required to enable some commands.

This migrates the net options away from the main Kconfig to net/Kconfig,
rename the current NET option to NET_LEGACY to really highlight what it
is and hopefully encourage more people to use lwIP, add a new NET
menuconfig (but keep NO_NET as an alias to NET=n for now) which then
allows us to replace all the "if legacy_stack || lwip_stack" checks with
"if net_support" which is easier to read and maintain.
The only doubt I have is wrt SYS_RX_ETH_BUFFER which seems to be needed
for now even when no network is configured? Likely due to
include/net-common.h with PKTBUFSRX?
No change in behavior is intended. Only change in defconfig including
other defconfigs where NO_NET=y or NET is not set, in which case NO_NET
is not set or NET=y should be set in the top defconfig. Similar change
required for config fragments. See commit log in patch adding NET
menuconfig for details.
This was tested based on 70fd0c3bb7c2 ("x86: there is no
CONFIG_UBOOT_ROMSIZE_KB_12288"), from within the GitLab CI container
trini/u-boot-gitlab-ci-runner:noble-20251013-23Jan2026 and set up
similarly as in "build all platforms in a single job" GitLab CI job.

O=../build/u-boot/ ../u-boot.sh -b master^..b4/net-kconfig |& tee ../log.txt
I can't really decipher the log.txt, but there's no line starting with
+ which would be an error according to tools/buildman/builder.py help
text. Additionally, because I started the script with set -e set and
because buildman has an exit code != 0 when it fails to build a board,
and I have the summary printed (which is the second buildman call), I
believe it means all builds passed.
The summary is the following:
aarch64: (for 537/537 boards) all +0.0 rodata +0.0
uniphier_v8 : all +1 rodata +1
u-boot: add: 0/0, grow: 1/0 bytes: 1/0 (1)
function old new delta
data_gz 10640 10641 +1
arm: (for 733/733 boards) all -0.0 rodata -0.0
uniphier_v7 : all -1 rodata -1

u-boot: add: 0/0, grow: 0/-1 bytes: 0/-20 (-20)
function old new delta
data_gz 15783 15763 -20
As far as I could tell this data_gz is an automatically generated array
when CONFIG_CMD_CONFIG is enabled. It is the compressed .config stored
in binary form. Because I'm changing the name of symbols, replacing a
menu with a menuconfig, additional text makes it to .config and the
"# Networking" section in .config disappears.
Here is the diff for the 5 defconfigs listed above, generated with:

diff --unified=0 $f/.config $(dirname $f)/$(basename -a -s '-m' $f)/.config

(-m is the build directory for master, and without the suffix, it's the
top commit of this series)

Highlight that NET really is the legacy networking stack by renaming the
option to NET_LEGACY.
This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise
CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL.
The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is
using the legacy networking app so this seems fine to do.
This also has the benefit of removing potential confusion on NET being a
specific networking stack instead of "any" network stack.

While moving it to head of flash.bin, other changes are required,
u-boot.itb is put at sector 768 per defconfig, so u-boot.itb binman
offset should be updated and it should be moved out from binman section.
Also binman symbol address are updated, so need to subtract u-boot-spl

When the J784S4-EVM is configured for PCIe Boot, the Bootloaders are to
be written to the address specified by particular BARs. The existing
documentation hard-codes the address corresponding to the BAR under the
assumption that the Root-Complex transferring the Bootloaders is also
a J784S4-EVM. The Root-Complex assigns addresses to the BARs depending
on the currently available set of free system addresses. Since the free
system addresses vary with the Root-Complex being used, instead of
hard-coding the BARs, automate the process of identifying the appropriate
BAR in the form of a command to be run by the user on the Root-Complex.

Currently entries.rst and bintools.rst are generated manually by running
'binman entry-docs' and 'binman bintool-docs', then committed to the
repo. This means the docs can drift out of date when docstrings are
updated but the RST files are not regenerated.
Add a Sphinx extension (binman_docs) that provides two custom
directives:
.. binman-entry-docs::
.. binman-bintool-docs::
These parse the etype and btool source files using the ast module to
extract class docstrings, then insert the documentation directly into
the document tree. This avoids the need to import binman modules (which
have dependencies like libfdt that are not available in the ReadTheDocs
build environment) and avoids writing any intermediate files.
